A classic Speedtest will perform a test of your connection on a brief moment which is not very precise when you know that a connection can vary over several seconds.

The speed.shadow.guru makes it possible to see details that are missing from the other Speedtest available on internet. There are very precise tests like nperf but the advantage of using ours is to be able to "ping" a Shadow server directly.

This is what a speed.shadow.guru looks like:

Your IP address

At the very top, under "Easy Speedtest" you will see your local IP address.

It will show that this speedtest was performed on a local machine and not on your Shadow.

The curves determining your bandwidth in Mb/s

This first graph shows you these two flows and their evolution over time.

The blue curve represents your downstream

Download is the flow of internet data you receive on your line. It's what drives, among other things, the speed at which you surf the internet, watch movies in HD, streaming and download heavy files.

The yellow curve represents the upstream .

Upload is the flow of data you send from your line, over the internet. You use it for example, to send e-mails, share photos on social networks, keystrokes, mouse clicks.

The curves that determine your ping and your Jitter in milliseconds (ms)

This second graph shows you your ping and your jitter.

The green curve represents your ping which evolves in real time.

Ping is the average time required to send a message that will arrive on the targeted computer server so that the server then receives it and sends it back in the opposite direction.

The red curve allows you to see your jitter in real time.

Jitter is the average of packet loss over a given time.

With this you can see in real time how many packets you lose on average during the test .

___________________

In any case, having both highs is a bad sign. A high jitter implies that a lot of data sent gets lost along the way, so that when the information arrives, it is missing vital elements. For example: If I press a key to move forward and then stop, the information to stop doesn't reach the server because it was lost and my character will continue to advance even after I stopped pressing the key.

A high ping will impact the time it takes for your Shadow to receive the information that's being sent. To reuse the example above, the character will take a while to stop moving even when we'd stopped pressing the key for some time before.

This kind of disruption on your line can strongly impact your Shadow experience which depends a lot on the stability of your connection.

Here is an example of a connection test in each case.

Good

Bad

That's it, you now know everything about speedtest.shadow.guru !

All you have to do is press "Run speedtest" to know your connection precisely when the support agents need it!
